The eighth overall pick out of Texas A&M directed the only touchdown drive on the six possessions that started at the offense's 30-yard line. The touchdown came on a 26-yard pass that showcased Tannehill's athleticism.

He rolled out of the pocket and scrambled right, and as he approached the sideline, he floated a pass to tight end Anthony Fasano over linebacker Gary Guyton.

“It was really impressive,” Fasano said. “It was a great touch pass on the run. I've said it all along, and I think everyone has said it — he doesn't really play like a rookie quarterback.”

Tannehill had the best day of three quarterbacks battling for the starting job. He completed 8 of 10 passes for 77 yards. Returning starter Matt Moore was 5 of 10 for 25 yards, and veteran free-agent acquisition David Garrard was 7 of 12 for 50 yards.

None of the quarterbacks threw an interception, although Garrard and Tannehill had potential interceptions dropped by the defense.
